    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I have a 1979 GS-850G. It runs great, but it appears the headlight really varies in intensity through the rev range leading me to think maybe its time for the {much touted} stator/voltage regulator change. As far as I know these are the original units - and since I have made sure my motor in sound and in good "nick" - the electrical system is what is supposed to be the weak link in the GS chain. What's the collective thought on this?

Yah, will dim at idle, increase some at 2000 and increase more from there as go to 3000 or 3500, but should be same from there up to max. So not neccesarily anything wrong. Actaully the fact that brightens when revs from idle tell you the cahrging is working. If it did not brighten - then, you got a problem.

You have a late 70s charging system, and a 30 year old late 70s charging system. Were much better than 50 & 60s charging systems when most bikes didnt have starter motors anyway.

The 80s were a bit better (when also had headlight on all the time, and no kickstarter), but not a lot better.

But, yeah, get a multimeter, and do the charging system check.
